IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 146,553, dated January20, 1874; application filed June 10, 1873.

To all 'whom it may concern:

Be it known that I, JAMES RIGBY, of Cincinnati, in the county ofHamilton and State of Ohio, have invented a new and Improved Gas-Burner;and I do hereby declare that the following is a full-and exactdescription of the saine, reference being had to the accompanyingdrawings and to the letters of reference marked thereon.

This invention is designed to insure the more perfect combustion of thellame, and, by thus producing more light, to economize the gas. Itconsists `mainly in the employment, in combination with a central tip,of a smaller tip upon each side, arranged on the same horizonf vtalline', or a little below it, but set at an acute angle relatively t'othe central tip, as will be fully described hereinafter.

In the drawings, Figures 1 and 4 represent side elevations of myimproved burner; Fig. 2 a sectional elevation, and Fig. 3 an endelevation, of the same.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe fully its construction and manner of operation.

A represents a central tip, and a c side tips, all of which areconnected to the maintube A, as shown. The side tips are smaller thanthe central tip, preferably in about the proportions of one to two, andthey are located in the same horizontal line as the central tip, or alittle below it. They are also set at an acute angle relatively to thecentral tip, as shown. If dehowever, they may be arranged vertically, asshown in Fig. 4, with slots so cut as to deliver the gas at a properangle.

y The operation is as follows: When theburner ,is in use, the largerportion of the gas passes through theicentral tip and forms the mainflame, the remaining portion of the gas passing through the side tipsand producing a small ilame, which is discharged against the dark orunconsumed portion of the main ame. In consequence of this action, thedark portion of the main flame is supplied with the requisite oxygen,and the hydrocarbons ordinarily unconsumed are ignited and burned, theilanie consisting wholly or almost wholly of white light. i

It is essential that these `supplemental tips be arranged in the samehorizontal line as the 'main tip, or a little below it, in order thatthe oxidizing portion of their iiames may strike the dark portion of themain ame at the proper angle to augment the flame. For` the same reason,also, it is desirable that these llames should beof smaller size,

tions is reduced.

each side of the central tip is advantageous,

because by this means the pressure upon each side of main liame is madeequal, and it is, in a measure, supported thereby, so as to be unaected,to a certain degree, by drafts, while, in the use of a singlesupplemental iame, it has been found, in practice, that, when exposed todraft, the flame would assume a curved form and smoke at the edges.`

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The described burner, having the branching head attached to the centraltube, and the cen` tral tip A and side tips a a, the auxiliary side ytips being inclined toward the main tip, asxdescribed, for the purposeset forth.

This specification signed and witnessed this 9th day of June, 1.873. Y
